The Wabaunsee Group is a Late-Carboniferous geologic group in Kansas, extending into Nebraska, Iowa, Missouri, and Oklahoma. The unit is recognized in the subsurface by drillers in Colorado as Wabaunsee Formation.
In locations, some upper members are not present due to a series of erosions that occurred in late-Pennsylvanian time.Classification of Rock in Kansas, Kansas Geological Survey, 1986 (Revised November 2018).Note: The chart illustrates the series of erosions beginning within the Willard Shale.
